What are some types of AI technologies?
AI apps and technologies have increased exponentially in the last few years. Below are some examples of common AI technologies you may have encountered.
History of AI
In his 1950 paper, "Computing Machinery and Intelligence," Alan Turing considered whether machines could think. In this paper, Turing first coined the term artificial intelligence and presented it as a theoretical and philosophical concept. However, AI, as we know it today, is the result of the collective effort of many scientists and engineers over several decades.
1940-1980
In 1943, Warren McCulloch and Walter Pitts proposed a model of artificial neurons, laying the foundation for neural networks, the core technology within AI.
Quickly following, in 1950, Alan Turing published "Computing Machinery and Intelligence," introducing the concept of the Turing Test to assess machine intelligence.
This lead to graduate students Marvin Minsky and Dean Edmonds building the first neural net machine known as the SNARC, Frank Rosenblatt developed the Perceptron which is one of the earliest models of a neural network, and Joseph Weizenbaum created ELIZA, one of the first chatbots to simulate a Rogerian psychotherapist between 1951 and 1969.
From 1969 until 1979 Marvin Minsky demonstrated the limitations of neural networks, which caused a temporary decline in neural network research. The first "AI winter" occurred due to reduced funding and hardware and computing limitations.
1980-2006
In the 1980's, there was a renewed interest and government funding for AI research primarily in translation and transcription.During this time, expert systems, like MYCIN, became popular because they simulated human decision-making processes in specific domains like medicine. With the 1980's revival of neural networks, David Rumelhart and John Hopfield published papers on deep learning techniques showing that computers could learn from experience
From 1987-1997, due to other socio-economic factors and the dot-com boom, a second AI winter emerged. AI research became more fragmented, with teams solving domain-specific problems across different use cases.
Starting in 1997 to about 2006, we saw significant achievements in AI including IBM's Deep Blue chess software defeated world chess champion Garry Kasparov. In addition to this Judea Pearl published a book that included probability and decision theory in AI research and Geoffrey Hinton and others popularized deep learning, leading to a resurgence in neural networks. However, commercial interest remained limited.
2007-Present
From 2007 to 2018, advancement in cloud computing made computing power and AI infrastructure more accessible. It led to increasing adoption. innovation and advancement in machine learning. The advancements included a convolutional neural network (CNN) architecture called AlexNet, developed by Alex Krizhevsky, Ilya Sutskever, and Geoffrey Hinton winning the ImageNet competition, showcasing the power of deep learning in image recognition and Google's AlphaZero mastered the games of chess, shogi, and Go without human data, relying on self-play.
In 2022, chatbots that uses artificial intelligence (AI) and natural language processing (NLP) to have human-like conversations and complete tasks like OpenAI's ChatGPT became widely known for its conversational abilities, renewing AI interest and development.
AI in the future
Current artificial intelligence technologies all function within a set of pre-determined parameters. For example, AI models trained in image recognition and generation cannot build websites.
Artificial general intelligence (AGI) is a field of theoretical AI research that attempts to create software with human-like intelligence and the ability to self-teach. The aim is for the software to perform tasks for which it is not necessarily trained or developed.
AGI is a theoretical pursuit to develop AI systems with autonomous self-control, reasonable self-understanding, and the ability to learn new skills. It can solve complex problems in settings and contexts that were not taught at its creation. AGI with human abilities remains a theoretical concept and research goal. It is one possible future of AI.

It is the science of developing algorithms and statistical models to correlate data. Computer systems use machine learning algorithms to process large quantities of historical data and identify data patterns. In the current context, machine learning refers to a set of statistical techniques called machine learning models that you can use independently or to support other more complex AI techniques.
Deep learning
Deep learning takes machine learning one step further. Deep learning models use neural networks that work together to learn and process information. They comprise millions of software components that perform micromathematical operations on small data units to solve a larger problem. For example, they process individual pixels in an image to classify that image. Modern AI systems often combine multiple deep neural networks to perform complex tasks like writing poems or creating images from text prompts.
How does artificial intelligence work?
Artificial intelligence systems use a range of technologies to work. The specifics vary, but core principles remain the same: they convert all data types, such as text, images, videos, and audio, into numerical representations and mathematically identify patterns and relationships between them. Hence, artificial intelligence technologies require training - they are exposed to large volumes of existing datasets to "learn" — similar to humans learning from existing knowledge archives. Some of the technologies that make artificial intelligence work are given below.
Neural networks
Artificial neural networks form the core of artificial intelligence technologies. They mirror the processing that happens in the human brain. A brain contains millions of neurons that process and analyze information. An artificial neural network uses artificial neurons that process information together. Each artificial neuron, or node, uses mathematical calculations to process information and solve complex problems.
Natural language processing
Natural language processing (NLP) uses neural networks to interpret, understand, and gather meaning from text data. It uses various computing techniques that specialize in decoding and comprehending human language. These techniques allow machines to process words, grammar syntax, and word combinations to process human text and even generate new text. Natural language processing is critical in summarizing documents chatbots, and conducting sentiment analysis.
Computer vision
Computer vision uses deep learning techniques to extract information and insights from videos and images. You can use it to monitor online content for inappropriate images, recognize faces, and classify image details. It is critical in self-driving cars and trucks to monitor the environment and make split-second decisions.
Speech recognition
Speech recognition software uses deep learning models to interpret human speech, identify words, and detect meaning. The neural networks can transcribe speech to text and indicate vocal sentiment. You can use speech recognition in technologies like virtual assistants and call center software to identify meaning and perform related tasks.
Generative AI
Generative AI refers to artificial intelligence systems that create new content and artifacts such as images, videos, text, and audio from simple text prompts. Unlike past AI, which was limited to analyzing data, generative AI leverages deep learning and massive datasets to produce high-quality, human-like creative outputs. While enabling exciting creative applications, concerns around bias, harmful content, and intellectual property exist. Overall, generative AI represents a major evolution in AI capabilities to generate human language and new content and artifacts in a human-like manner.
